John Williams’ score for “Disclosure Day” marks his 30th collaboration with Steven Spielberg, a partnership that stretches back to their first film together, “The Sugarland Express,” in 1974. At 94, Williams is now widely viewed as one of the great living icons of film music, and although no official announcement has been made that this is his final movie score, the possibility has surrounded the project for years. Spielberg has reportedly already discussed the idea of a 31st collaboration with him, even after Williams suggested several other composers as potential successors.
According to multiple sources, Spielberg was determined to have Williams score “Disclosure Day” and arranged a longer-than-usual production schedule to accommodate him. Instead of the typical one- or two-week film scoring window, the music was recorded across seven sessions over roughly six months, giving Williams time to shape the score carefully. Williams, who has faced health challenges in recent years and is now often seen in public using a wheelchair, is said to have approached the project with strong energy and attention to detail.
The sessions began on Sept. 11, 2025, at Sony’s scoring stage in a facility now named the John Williams Music Building. A 96-piece orchestra was assembled for the recordings, along with a 30-voice female choir added later in the process. The instrumentation included traditional symphonic elements, but also featured unusual details such as four bassoons for a particularly dark cue, as well as piano, celeste, synthesizer, and two harps. The choir’s wordless vocals were recorded together with the orchestra, reflecting Williams’ preference for capturing all elements in the same room.
Sources say Williams orchestrated the score himself and conducted much of it, sometimes seated but occasionally standing. Longtime collaborators William Ross and Randy Kerber were credited with orchestration and conducting in the film’s credits, but those familiar with the process say their contributions were limited to adaptations required by revisions. Spielberg was reportedly present for the sessions and closely involved, offering musical input and working directly with Williams and music editor Ramiro Belgardt while watching the film on a small shared screen.
The final score runs 82 minutes in the film, though Williams recorded more than two hours and 20 minutes of music, with some material saved for the soundtrack album. The music is described as restrained, atmospheric, and sophisticated, with a contemplative main theme that carries an Americana flavor suited to the film’s middle-American setting. The score also includes eerie string writing and subtle dissonance that recalls “Close Encounters of the Third Kind,” while darker and more urgent passages support the film’s government conspiracy elements and the flight of the main characters, played by Emily Blunt and Josh O’Connor.
“Disclosure Day” is Williams’ 105th theatrical film score, adding to a career that began in 1958. He has earned 54 Oscar nominations and five wins, along with 76 Grammy nominations and 27 wins. In recent days, his latest concert work, “Bravo Gustavo,” was premiered by the Los Angeles Philharmonic. Spielberg reportedly said at the end of the final session that the pair were still “in love” after 30 films together, underscoring one of the most enduring creative partnerships in cinema.
